A = P(1+r/100)to the power n
2646 = 2400(1+5/100)to the power n
2646/2400=(21/20) to the power n
441/400=(21/20)to the power n
(21/20) to the power 2 = (21/20) to the power n
= n = 2yrs
2646 = 2400(1+5/100)to the power n
2646/2400=(21/20) to the power n
441/400=(21/20)to the power n
(21/20) to the power 2 = (21/20) to the power n
